Rhodium(III) sulfide is the inorganic compound with the formula Rh₂S₃. It is an insoluble black solid, prepared by the heating a mixture of elemental rhodium and sulfur. Crystals can be grown by chemical vapor transport using bromine as the transporting agent. The structure consists of octahedral and tetrahedral Rh and S centers, respectively. No close Rh-Rh contacts are observed. Rh₂Se₃ and Ir₂S₃ adopt the same structure as Rh₂S₃.
